There are number of read/write data which could even be encrypted. supermarkets in each city having a huge amount of people These tags could hold plenty of data like products visiting on a daily basis. Now a days purchasing and name, price, size, weight and other information using shopping at big malls is becoming a daily activity in metro their identification number. By implementing this cities. It is seen that there is a huge rush at malls on holidays RFID technology for unique representation of each and weekends. The rush is even more when there are special product in a market shopping is done more easily. offers and discount. The payment of bill by standing in long RFID (Radio Frequency Identification) technology queue is a tedious factor. The existing system is the Barcode provides ability to many new services and quality in technology in which the barcode must be in the direct line of the busy environment. The paper discuss about the sight to be read by barcode scanner. Barcode have no RFID implementation system used for bulk billing at read/write capabilities and can be easily reproduced, which results in less security. If the barcode is ripped, damaged malls or markets. This will enable the consumers there’s no way to scan the product. To overcome this, the satisfaction, reducing time requirement for payment proposed system uses radio frequency identification and also the manpower required at markets or malls technology that has gained position in various innovative by instantly payoff their entire purchase upon arrival applications that also results in the speed of handling at the payment counter, increasing customer. These manufactured goods and materials. RFID can detect the RFID tags are utilized to automate the checkout tags using RFID reader from distance without the line of process by building a system that could read the sight. It allows contact less detection of the objects using the RFID signals of all the objects that would be placed in radio frequency and supports the read/write memory proximity to an antenna platform. This eliminates the capability and it can hold large amount of data under a need for barcode scanning of each individual item, unique identifier. Using the RFID technology the time of people in queues will be reduced to 1/3rd of the total time making checkout a significantly faster experience. taken to stand in the queues. People can place all their The tags are little in size and so it can be easily products on the plain area where an RFID reader will be pasted on products RFID tags are an improvement placed which will be scanning all the items having RFID tags over barcodes since you can update or change the simultaneously and automatically updates the details of information on the tag. Since it communicates with each item into the computer. Thus, a single person is enough the network, it can take the data stored on it change at the billing section just to print out the bill and hand it it to something new. The network connected to the over to the customer other than having three people at each reader can update or change the data stored on the counter. Thus, reduces the overall waiting time of the RFID tag if necessary. customers and enable a better shopping environment for the customers.

1.1 PROBLEM FORMULATION

Key Words: RFID, POS, UHF, GUI, IDE

The use of barcodes in the retail industry all started back in the late 1940’s and early 1950’s to figure out a way to acquire product information when a customer checked out groceries. Barcodes became commercially successful when they were used to automate supermarket checkout systems, a task for which they have become almost universal. Their use has spread to many other tasks that are generically referred to as automatic identification and data capture (AIDC). In stores, barcodes are pre-printed on most items other than fresh produce from a grocery store. This speeds up processing at check-

1. INTRODUCTION These days, RFID's are widespread and taking role in many advanced projects due to its fast and effective response. RFID are generally tags that are used for unique identification of products by using radio waves. These RFID's offer more advantages over conventional Barcodes as they have a major drawback which is Line of sight technology and also © 2020, IRJET

outs and helps track items and also reduces instances of shoplifting involving price tag swapping, although shoplifters can now print their own barcodes. Yet barcode system has their own disadvantages. Label damages, less information storage, human effort and line of sight provides the basic issues faced by the barcode system. In order to overcome this issues. Our project proposes a RFID based POS system. 

Barcodes are designed to be scanned one at a time whereas many RFID tags can be scanned at once.



Barcodes require that the scanner maintain a lineof-sight with each code, while RFID is a “near field” technology, so the scanner only needs to be within range of the tag to read it.



Barcodes are generally printed on paper or adhesive labels, so they are prone to wear and damage, while an RFID tag is generally a tougher product that can withstand more abuse.



The type and volume of data on barcodes is more limited than what can be stored on an RFID tag.

2. PROPOSED SYSTEM RFID based pos system aims at increasing the efficiency and productivity of retail shops, mainly for large shopping malls where people face the issue of time consuming process at the checkout area. Unlike the barcode system, this system provides much faster way of checkout at the billing counter. The system includes RFID tags attached to each product in the shop which contains a unique ID that helps to retrieve information about the particular product from the database. The salesperson can login to his account using the provided username and password. Once logged in, salesperson can access the billing page on which he/she can run the purchase orders. The salesperson will place the products on to his table where RFID reader is placed. Once the products are placed to the area on the table, RFID reader starts capturing the data, matchup with the data stored in the database. The application will automatically generate the invoice based on the captured data. The invoices are produced by reading the data from the RFID reader using java listeners in the java program written for desktop application. Salesperson can place the order and mark order as completed.

On the other hand, the advantages offered by RFID have made it very popular in recent years, especially for people who’ve been working with barcodes for some time and have faced frustration due to its inherent limitations.

1.2 OBJECTIVES The objective of this project is to create an RFID POS system to improve the speed of purchase in retail business, also to reduce the workload of the staffs and hence increase the productivity. As per a survey conducted by University of Oklahoma in 2015, 80% of customers are frustrated being in long queues. Hence, the GDP growth of retail industry has been reduced to 1.6%.

The current barcode system and the outdated technologies in retail business are the main issues of this decreased rate. The proposed system built on top of integrated RFID will be the right replacement for the existing barcode and outdated technologies used by retail shops. RFID POS provides easy and fast scanning of products and fast generation of invoice at the billing counter. This will reduce the queue at the billing counters of retail shops and hence increase the productivity. Hence, customers are freed from the stress of waiting on a long line of queue to get the billing counter, thus avoiding all the RUSH, HUSTLE, WAITING and STRESSING, "The main tensions u want to avoid in shopping ".

Key Features are: 1.

Faster and easy billing

2.

No WAITING for billing : Faster exit

3.

Automated instantaneous CURRENT TOTAL on display : better budget calculation #

as this data can provide insights on which customer would be interested in the sale.

B. SALES ORDER This module used in the system will capture all the sales order simultaneously and automatically generate the invoice once the products are placed upon the RFID reader. There should be an option to place order manually in case RFID isn’t responding. That is the order will be added manually by the staff at the counter if RFID fails to read. The Sales Orders module allows you to store details of orders that have been received from the customers.

Then the system will automatically generate customer invoice upon capture of the products.

C. INVENTORY MANAGEMENT The module help us to add, edit, delete…etc products.

Inventory management makes a systematic approach to sourcing, storing and selling finished products. The module helps to get the right stock at the right levels at the right time. The module has 4 sub-modules such as category, product label, payment mode, tax. The category allows to add unlimited product categories such as soaps, biscuits, chocolates..etc. The product label module allows the user to create labels of the product such as dettol soap, bourbon biscuits, munch..etc. The tax management module help us to manage tax of the product such as gst,sgst..etc.

The added tax will automatically apply on the product. The payment module manages the payment types such as cash, credit card..etc.

B.UHF RFID TAG These paper-thin EPCglobal Gen2 tags work with our Simultaneous RFID reader. The tags can read and be written to --- and also have a kill feature. Each tag comes with a TID (Truly Unique ID) that can't be changed, but there's plenty of memory to write and read from.

D. SCENE BUILDER JavaFX Scene Builder is a visual layout tool that lets users quickly design JavaFX application user interfaces, without coding. Users can drag and drop UI components to a work area, modify their properties, apply style sheets, and the FXML code for the layout that they are creating is automatically generated in the background. The result is an FXML file that can then be combined with a Java project by binding the UI to the application’s logic.SceneBuilder is used to create the GUI layout of the system’s application.

The idea was to bring user friendly layout for the software, replace with default java layout. SceneBuilder was one of the choices to design the screens for the software since it has modern elements which would add user friendness of the application.

2.3 RESULT

Fig -5 Auto Billing Page

The system will have a username and password for the admin/staffs to login. For admin, he/she gets access to all the modules under the POS module. For other staffs, the access to modules depends upon the user roles and permissions assigned to each of them. For a sales person,.

Once the login has been established, he/she gets access to the POS module. The POS module will have sub-modules like reports, sales order, customer management, staff management and user roles. Then the salesperson will have access to the sales order and customer management modules. In the sales order module, an integrated RFID is been used to capture the products. Once the device is connected with the system, the listener program in the software will listen and capture the products which has UHF RFID tags. The data will be filtered and sent to the database where a check will run against the added product in the inventory. Once the match is established, the system will automatically display the matched product on the POS billing screen. The system will filter out the quantities of same products, Eg: if a user is buying 5 pens, then a single row with pen will be displayed with quantity 5. Then the salesman can generate invoice based on the purchase. In the inventory module, while adding products a unique 16 digit hexadecimal code will be generated for each product depending upon the quantity. With integrated RFID reader the system will write/read the generated hexadecimal code to each RFID tag.

3. CONCLUSION The proposed system is an efficient system for all retail business. Integrated RFID reader is one of the latest technologies in IOT domain which is been effectively used in retail logistics industry. By using RFID POS system, the growth of retail will be immensively high compared to the current barcode system. The system will reduce the customer queue in retail shops. Thus, increase revenue and customer satisfaction. Compared to current barcode system, the integrated RFID can capture data simultaneously upto 500 tags at a time. On the barcode system, each product has to go one at a time. The system is built using Integrated RFID Reader and software is built on top of Java. The software can be implemented on any Windows machine with USB port. A Web Server can be added as a future scope linked with the software which turn this product to a cloud based POS. All the transactions happening offline will be pushed to the server once it get an internet connection. In the software perspective, there are many future scopes such as advanced reporting system, notifications, invoice on to customer’s email, sms notifications, promotions and offers, coupon codes…etc. As an owner of retail business, he/she can access the backend from anywhere at anytime. Android and IOS versions of the software will be welcomed in many different countries such as Africa, USA..etc.
